Improve code readability with closures in Ruby

Code readability is a very critical parameter for any project maintainability. Serious business needs reacting to failures and fixing bugs as soon as possible. That allows not to lose old clients and make the service more attractive for new ones.But how to improve readability? One might think that installing, configuring, and following automatic tools such as Rubocop or Reek is more than enough. Indeed, these tools are great. They are highly recommended and really help a lot. Unfortunately, they are not a silver bullet. They cannot eliminate one important factor - distance to natural language. As closer code to natural language as better its readability. This is the measure everyone should strive to.
